This iceberg is calved from Kangerdlussuaq glacier, the largest glacier on the east coast of Greenland's ice sheet and probably the world's fastest moving glacier. Kangerdlugssuaq tripled its speed between 2004 and 2005, and is now rapidly moving mass out of the middle of Greenland's ice sheet, in the form of icebergs. This has urgent implications for both the mass balance of the Greenland ice sheet, and for the rate of sea level rise globally.
